气液分离器是重力供液系统关键的部件之一。为了揭示分散相在气液分离器中的分离机理，应用液滴动力学理论，对分散相在连续相中的受力和运动进行了分析，同时考虑了制冷系统气液分离器内部稳定流速的限制。分析表明：制冷系统中制冷剂气液两相重力分离过程基本处于 Allen 区；可忽略沉降过程中的重力加速效应，重力加速过程产生的位移很小，对于计算结果不会引起较大偏差；并以制冷剂R404A为例，得出了不同沉降区液滴粒径范围。

Gas-liquid separator is a key component of gravity feeding system. In order to obtain separation mechanism in gas-liquid separator, applying droplet dynamics theory,the received force and motion of disperse phase are analyzed. And the velocity limit in separator of refrigeration system is also considered. Analysis results shown that in the refrigeration system the separation process is basically in Allen region; the gravity accelerate effect can be negligible, and the displacement in the gravity accelerate process is small which can not cause large deviation of the calculation result. Take refrigerant R404A for example, the droplet size in different droplet settling area is obtained.
